This is a Dutch East Indies Undated Pre Stamp Outer Wrapper.  It's from the early to mid 1800s, and was sent to Reuban 3 with an address in Chinese and Dutch with chops.

Something special about this cover is is the OVAL TOEBAN FRANCO Marking in RED 327c.  It's in Fine to Very Fine Condition!

Take care because this item, though in very good shape, is still extremely old!
